This invention relates to improvements in window adj usters, and more especially storm Windows or screens, such as are hingedly hung from one portion of a window casing and adapted to be swung out so that the sash may be adjustably supported at various positions with respect to the lower portion or sill of the frame.

The object of the invention is to provide a simple and inexpensive form of window adjuster, of the-class specified which may be economically formed of sheet metal and adapted to be readily applied to both a window frame and hinged sash; further to provide an adjuster of the class specified which will be compact and applicable for attachment to the top of the window sill rather'than the side or top portions oi the window frame, and which, when so applied to the sill and sash, will lie close to the sill requiring a comparatively small amount of space and adapt-k ed to operate on a horizontalplane rather than a vertical plane.

The adjuster may be used Vsingly or in pairs, as preferred and may be used for the adjustment of thelower portion of either a 1 glass sash or a screen, hinged to swing out,`

and can be used either upon the bottom sill of a window frame or upon the under side of the top portion of the frame, if for any reason it may be necessary, or preferable to hinge the sash at the bottom instead of at the top.

The invention specifically resides in a window adjuster formed of relatively iiatmetal parts hingedly connected together, one end member of which is adapted for attachment to a window sill and the opposite end'member constructed to be secured to the inner face of the sash. The connected ends of the two main oldable arms of the adjuster vare hingedly connected to swing in a horizontal plane and upon a vertical pivotal pin, their outer ends being swivelly connected to said fixed members attached to said frame and sash, the said swivel connection allowing of both a horizontal swinging movement of said arms with respect to the xed members, as well as a vertical movement of the outer members of the adjuster, better to permit the outer end 1929. semaine. 371.166;
